Are nvidia's own website drivers better or third party drivers???

hi, can somebody tell me that drivers for AGP cards with ref to nvidia available on nvidia's own website are better to use or ones available on 3rd party websites are betters. For instance now a days the latest version of driver available on nvidia's website is 81.98, however, on some other sites e.g www.guru3d.com, latest version of driver i.e later version then 81.98 is available for nvidia cards. So my question is: is it better to go with the one available on nvidia's own site or the other one????

thnx :grinthumb

I only use the WHQL drivers on Nvidia's site. Newer versions may just be beta versions or modified (hacked) drivers.

thnx that means never use other drivers then the ones available on nvidia's own website.

The only time that using the card makers drivers would be better than using Nvidia's reference drivers would be if the card maker has deviated from Nvidia's reference design. Off hand I cant think of any video card makers that are doing so, but Nvidia does allow them that freedom.
